8.2 CE marking
Declaration of Conformity
The system housing described in the present
instructions, comply with the requirements and
the target of the following EU directive and
with the following harmonized European
standards:
•Low Voltage Directive 2006/95/EC
This product is a built-in unit which, owing to
its installation characteristics, is not able to
comply with the regulations for complete appa-
ratus, machines or installations from the outset.
For this reason, it may only be used for built-in
purposes. The product may only be assessed
with regard to its electrical and mechanical
safety as well as to environmental effects (for-
eign bodies, moisture) after it has been in-
stalled in the product intended for the final us-
er. After the product has been installed, its
EMC properties may change. Hence the prod-
uct intended for the final user (complete appa-
ratus, machines or installations) should be in-
spected with regard to its EMC properties by
the manufacturer of the product intended for
the final user.
•EMC Directive 2004/108/EC
Maintaining the EMC directive presuppose an
EMC adapted installation of the devices within
the installation of the machine. The complied
limit values and standards are specified in the
Rexroth Manual of associated product. The
regulations for the structure and the installation
in this manual must be maintained and real-
ized. Tests were run using a typical installation
in a test assembly that conforms with the
standards. These Rexroth products are built-in
devices for a product for the final user. The test
results cannot be transferred to every state as
installed in every product intended for the final
user. This declaration does not therefore assure
the EMC characteristics of the product for the
final user.

A fuse must be installed between the pow-
er supply output voltage and the drive power
input voltage connection. The rating of the fuse
depends on the used cables and application re-
quirements of the motion profiles.
•Fuse rating for UL fuses
Fuses must be certified for DC rating, Fast
Acting, and have to be UL recognized under
CCN JDXY2/8. Secondary fuses also have to
be UL certified for DC rating.
•Fuse rating for IEC fuses
Fuses must be certified for DC rating, Fast
Acting, and have to be IEC 60127-1 certified.
Secondary fuses also have to be or IEC certi-
fied for DC rating.
Wire gauge and wire diameter as a func-
tion of ambient temperature are derived from
the NFPA-79:2012. Insulation temperature of
wires is assumed to be 60 °C (140 °F) or 75 °C
(167 °F).
If using wires with an AWG smaller than
or equal 12, or a diameter larger than or equal
2 mm2, two pins for (+) and (-) must be used
on the drive power connector.
9.7 M – Motor connections
______________________________________
Voltage on the pins of
this connector can be higher than 60V DC.
Do not touch the pins of this connector.
Do not touch the rear side of the I/O backplane.
______________________________________
Always use shielded cables for motors con-
nected to the drive modules.
Make sure that the motor cable of suitable
AWG marking is used, taking into account the
number of separate wires in the cable and the
maximum rated current.
Every motor cable must be connected on
the system housing with a motor cable shield
and support bracket.
Connect the shield at the system housing side
to the motor cable shield and support bracket,
and connect the shield at the other end to the
motor housing. If the housing of the connector
at the motor side is made of non-conducting
material, connect the shield from the connector
at the end of the cable coming from the system
housing side to the metal mounting plate on
which that motor is mounted.
Wire gauge and wire diameter as a func-
tion of ambient temperature are derived from
the NFPA-79:2012. Insulation temperature of
wires is assumed to be 60 °C (140 °F) or 75 °C
(167 °F).
9.8 MUX – HALL sensors
Always use shielded cables with twisted pairs
for the differential signals. Connect the shield
at the system housing side to the metal con-
nector housing.

9.10 Dig/Fdig – 24V power supply for Digital I/O
and Fast Digital I/O connections
The 24V SELV power supply for the digital
I/O and fast digital I/O connections are on the
connectors ‘DIG/FDIGx’.
______________________________________
The system housing has
no provisions against wrong polarity con-
nection of the 24V I/O power supply voltage.
Observe proper polarity when connecting the 24V
I/O power supply.
______________________________________
A fuse must be installed between the 24V
SELV power supply output voltage and the
24V I/O power input voltage. The rating of the
fuse depends on the used cables and total cur-
rent.
Fuses must be certified for DC rating, Fast
Acting, and have to be UL recognized under
CCN JDXY2/8 or IEC 60127-1 certified. Sec-
ondary fuses also have to be UL or IEC certi-
fied for DC rating.
Wire gauge and wire diameter as a func-
tion of ambient temperature are derived from
the NFPA-79:2012. Insulation temperature of
wires is assumed to be 60 °C (140 °F) or 75 °C
(167 °F).
All external connected inputs and outputs
shall be separated from hazardous live by dou-
ble or reinforced insulation.
Shielded cables are mandatory for fast
digital I/O connections. Shielded cables are
recommended but not mandatory for digital
I/O connections. If shielded cables are used,
connect the shield at the system housing side to
the connector housing. Connect the other end
to a convenient metal part or leave it uncon-
nected.
For fast digital I/O signals, the cable with
the signal wire(s) should also contain the return
current path for every signal in the cable. It is
allowed that a single wire carries the return
currents for more than one signal, as long as
the current rating of the wire is not exceeded.
These measures are also recommended for the
other digital I/O.
10 Installation and Removal
______________________________________
Damage to components
may occur if power is applied during instal-
lation or removal.
•Make sure power supplies are switched
off before installation or removal of the
system housing.
•Do not apply power until the system
housing is installed.
______________________________________
Power supplies must be switched on/off
with the disconnecting device installed in the
cabinet.
The system housing may only be used as
build-in equipment in a cabinet, which means
that the end-user must provide a suitable fire
and electrical safe enclosure. The safety of any
system incorporating the system housing is the
responsibility of the assembler of the system.
The system housing may only be used in
combination with external approved power
supplies. The supply voltages 24V System,
24V Dig, and 24V Fdig for the system must be
separated at least by reinforced insulation from
all hazardous voltages according to the stand-
ard UL61010-1 third edition.
10.1 Mechanical dimensions

10.2 Mechanical installation of the system housing
Make sure that you observe the minimum ven-
tilation space at the top, front and bottom side
of the system housing, see the picture.
≥100 mm (forced cooling)
F
L R
≥200 mm (convection cooling)
≥100 mm (forced cooling)
≥200 mm (convection cooling)
The minimum distance above and below the
system housing is required for cooling. Bend
all cables connected below the module holder
away from the ventilation holes as near to the
connectors as possible. Free clearance space in
front of the module holder (“F”) is needed for
the optional strain relief bracket and for bend-
ing IEEE 1394b cable(s). As a rule of thumb,
100 mm is sufficient. The free distance on the
right (R) and left (L) of the system housing
must be sufficient to access the connectors at
those sides. For convection cooled systems the
system housing must be installed vertically to
allow free air flow from bottom to the top. For
forced cooled systems it is allowed to install
the system housing horizontally.
Install the system housing on a vertical
metal surface, and ensure electrical contact be-
tween the system housing and this surface, ei-
ther by means of washers under the screw
heads or use the protective earth post on the
system housing with washers and nuts. Ensure
that there is electrical contact between the sys-
tem housing and the mounting base of all other
equipment installed on the metal frame or
mounting base.
Each protective earth connection may be
routed in the most convenient manner for the
equipment concerned. The NYCe 4000 system
puts no extra requirements on the protective
earth wiring – no central earth point or similar
constraint.

First connect the 24V power supply plug.
Then connect the drive power supply plug.
10.3 Protective Earth connection
For safety reasons, the protective earth connec-
tion via the threaded earth post is mandatory.
The protective earth connection must be
connected before any other cables are connect-
ed to the system housing.
The protective earth connection must be
realized using an as short as possible cable, or
better a braided band, with a faston at the sys-
tem housing side.
The protective earth connection is fastened
on the M5 threaded post on the system housing
using a ring, the faston with the cable or the
braided band, a spring washer and a nut, in that
order. Tighten the nut with a nut spanner.
You must adhere to the installation re-
quirements of your country.
10.4 Motor connection
Always use shielded cables for motors. All
motor cables must be connected with the motor
cable shield and support bracket using the fol-
lowing mounting instruction.
1. Strip the wires of the motor cable accord-
ing to the following picture.
AB
XY
Strip the cable coating for a length of
50 mm.
Strip the shield for a length of 40 mm.
The shield length is 10 mm, the wire
length is 40 mm.
2. Put the wires of the motor cable into the
motor connector according to the instruc-
tions of the connector manufacturer.
Keep the wires of the motor cable to the
connector as short as possible (!).
Securely attach the motor cable to the
shield and support bracket .

E!
Use the tie-wrap with the EMC gasket
to clamp the shield of the cable against
the metal bracket.
Use the standard tie-wrap to attach the
cable firmly onto the metal bracket.
3. Put the hook of the shield and support
bracket into the slit at the left side of
the header on the metal base of the sys-
tem housing. Lock the shield and support
bracket onto the base plate with the
screw .

10.5 MUX connection
Connect the shield of the MUX cables to the
metal housing of the sub-D connector. Use
twisted pair cabling for the differential signals.
10.6 PTC connection
Connect the shield of the MUX cables to the
metal housing of the sub-D connector.
10.7 Configuration
The configuration of the system housing de-
pends on the model. The left side of the system
housing is the side where the ‘24V System’
power supply connector is located.

In all system housings the slot on the left-
most side is called ‘MCU’ and is a slot dedi-
cated for the installation of the Motion Control
Unit (MCU).
The adjacent slots at the right side of the
MCU module in the module holder are drive
slots called ‘DRV0’, ‘DRV1’, for the drive
modules type NYM04.1-2PW-NNNN-
NY4120/10.
10.8 Mechanical removal of the system housing
______________________________________
Voltage on the pins
of the “DPx” drive power connector can be
higher than 60V DC. When the connector is
unplugged a high voltage can remain pre-
sent on the pins for 5 minutes after discon-
nection. If a drive slot has an accompanying
capacitor installed and the drive module is
not installed in that drive slot, you must
wait 30 minutes.
Do not touch the pins of this connector.
Do not touch the rear side of the backplane.
______________________________________
Make sure that all power supplies are switched
off and capacitors in the system are fully dis-
charged before you remove the system hous-
ing.
First, disconnect all drive power supply
connectors (“DP”). Then disconnect the 24V
System power supply connector. Finally, dis-
connect all remaining connectors and protec-
tive earth connections.
Remove the screws that mount the system
housing on the metal surface in the machine.
11 Commissioning
-Check that the system housing is mechani-
cally solid mounted in the machine.
-Verify that the protective earth connection is
correctly connected.
-Check that proper cabling is used.
-Check that appropriate fuses of correct rat-
ing are installed for drive power and digital
I/O power supplies.
-Check that power supply cables and motor
cables are installed with proper strain reliefs.
-Check that the shielding of shielded cables is
correctly connected.
-Check that cables are not damaged.
